Most places will tell you they won't accept payment plans, but they will. And usually. once you default, the fees stop.
You need to close the account. When you do that, ask your bank what their policy is on ach transactions going through on closed accounts. Some banks will force open the closed account and allow the transactions to go through. Then you end up owing the bank $1000's. If your bank does do this, tell them the whole situation, and ask them to put an ach block, deposit only, or a hard hold on the account before they close it. That will stop the pdl's from force opening the account.
You need to start taking care of the important things first. These are just loans. You can't go to jail, the worst that can happen is they take you to court and get a judgement. As long as they are recieving payments regularly, odds are against them doing so.
Just call them up and be honest. Things got out of control, and you can't handle it. You want to pay what you owe, but you need to set up more affordable payment plans.
